Specification of Letters Patent. -Patented J an. 25, 1921. Originalapplication filed July 23, 1919, Serial No. 312,806. Divided and thisapplication filed December a1, 1919. Serial no. 348,669.

To all whom it may concern Be it known that I, JOHN F RICK, a citizen ofthe United States, residing at Philadelphizncounty of Philadelphia, andState of ennsylvania, have invented a new and use ful Improvement inLiquid-Dispensing Apparatus, of which the following is a full,

clear, and exact description, reference being had to the accompanyingdrawings, which form a part of this specification.

The object of my invention is to provide a soda water vending machine,adapted to dis- I pense a measured quantity of flavoring syrup and ameasured'quantity of carbonated water, under pressure, into a properlypositioned cup.

The mechanism whereby the above objectsare attained is intended moreparticularly to be coin-controlled, and means whereby the deposit of acoin .renders said mechanism operative are shown, but the mechanism isreadily adaptable for use independently of coin control. In anapplication filed by me July 23,.

1919, Serial No. 312,806, of. which this application is a division, Ihave fully disclosed the present invention in association withcoin-controlled means for-delivering a'cup; the syrup and carbonatingwater dispensing mechanism being shown as depending for its operationupon the prior successive operations of inserting a coin and operatingthe cup delivery mechanism to deliver a cup and release the coin, andthe coin then so positioning itself as to render thesyrup "and waterdispensing mechanism operative. In

Fig. 5is a side view of part ofothe mecha-;

nism immediately controlled by a. coin.

Fig. 6 is a plan view of the coin discharge tank is located an uprightcylinder h inclos ing a tight fitting plunger 11 carried by a screw jthreaded in the cylinder head and retained. in any desired position bymeans of a. lock nut k. I

Apipe Z connects one of the horizontal cylinders c with a passage 1 inthe upper part of a valve casing m. A pipe n leading from the lower partof the valve casing has a Y branch leading to the bottom of cylinder h,the main line extending upward and out of the tank I) and terminating ina valve 0. A pipe 19 leads from the lower part of the valve casing andterminates in a muffler Q. Small holes r in the side of the pipeallowcommunication from the pipe to the muflier. A pipe svleads from themuffler, out through the casing (1 and terminates at a nozzle t, whichit partly incloses and beneath which is a cup holder 35. The end of thenozzle is protected by a shield at fastened to the casing.

The valve casing m is provided with two valve seats 11 and w and adouble-faced valve :12, above the top of which extends a pilot valve 2adapted to control passage 3 and facilitate the seating of the mainvalve on seat '2). It will be seen that when the valve is in its lowerposition its lower face will seat on seat 10, closing communicationbetween cylinder k and nozzle t, while its upper face and the pilotvalve will be clear of seat 1) and passage 3 affording communicationbetween cylinders c, the carbonated water supply 6, and cylinder h, andvice versa. A plug is threaded onto the head of valve casing m and maybe removed for' cleanin the valve.

A va l ve stem '3, integral with valve m, extends out of the casingthrough a stuffing box 4 and is fitted on the end with a yoke 5. Theyoke carries a spring-pressed tappet having a roller 6 on its end. Valvem is drawn into lower position by means of aspring 7 connected tobracket 8. Beneath -the roller is a horizontal shaft 10 carried bybracket 8 in suitable bearings. Pinned to theshaft is a cam 13 adaptedto act on the roller 6 and raise the valve against the action of spring7, which, when the high, point of the cam passes out of contact with thetappet, returns the valve to its lower position. A second cam 14 ispinned to the shaft and adapted to act on a block 15, provided with aroller 16 and slidable on the bracket ,8, against the action of a spring17, carried I fastened to a frame 26.

A well 27, provided with apassage 28 flush with the false bottom, ispositioned in 'the bottom of the container.

A plunger 29, having a stem 30, is fitted into the well, and a pipe 31leads from near the bottom of the well through the plunger and throughthe casing a, terminating in a plain nozzle 12 adjacent to thecarbonated water nozzle t, beneath shield u.- A lever 32,'pinn ed to afulcrum 33, is connected at 'on end to the end of plunger st'em 30 andat the other-end, through a pin and-slot, to a plate 34, suitablysecured to the end of shaft 10.

The coin-connected manually operated actnating mechanism for deliveringthe rup and carbonatedwater comprises a rac bar 66 in engagement withpinion 20. An ori-i' ficed block 67 surrounds the end of the mo bar. andcontains a coin slot at an angle therein glust'beyond the end of. theinclosed bar. Tfis block is adapted to be slid along the top of a coinchute 68 by ahand lever 72 pivoted to a suitable support and; having anarm. connected with the block by'slot an pin connection 69.

is entered into its coin slot, however, the

' coin, being larger in diameter than the rackv bar forms a stop. and inthe movementof the block the bar isalso. moved,turning 'other coin.acting to'cause the dispensing to ough'the action ofa pawl 21,-

ith a removable cover 24, and a false bottom pinion 10 and operating thedispensing valve.

- Chute '68 has an elongated opening 70 in its top face, underlyingblock 67 in its move: I

ment by the hand lever. This opening 69 is of such width for most ofitslength that the coin falls into the chute.- Opening 70 also serves thepurpose of allowing coins smaller than the coin with which the machineis intended to be used to fall directl from the slot in the block andprevent suc take place.

After the block has been made to travel '70 r it willnot permit thepassage of the coin in as described, it returns to its initial positionproviding a slot 66 in the bar adapted to act with a pin 71 in the blockto allow free movement of the block when moved without any coin beingentered.

- An arm 74 extends from the lever to which I? one end of a spring 75 isfastened, the other end'being fastened to the frame, to return andmaintain the lever in its initial position as shown in Fig. 2.

A ratchet 76 is formed on the lever adjacent the pivot having at one enda stop 77 and at the other end a .pawl trip 78. A pawl '79 is pivoted toa suitable support in position to act on the ratchet 76 as the handledescends, until the trip acts to throw it out of engagement, when thehandle reaches its lower limit. by a spring 81, engages the short arm ofthe pawl and holds it in engagement with the ratchet until the pawl istripped. I The detent then holds the pawl out of its ratchet engagingposition until the handle 'is raised and the stop 77 throws the pawlback into en agement with the ratche ivoted to the block engaging arm oflever 72 is a forked'ro'd83 engaging the shaft 10 with its forked endand having a shoulder 84 formed on itsJside. to act as' a stop for shaft10 through the medium of arm 85 carried by cam 14 and positioned tocontact with the arm when the rod 83 is fully ad- .vancedby the leverreaching its lower position. A dash pot 86 is positioned adjacent thelever 72 and connected with the block engaging arm to regulate the speedat'which the lever may "be moved. Ordinarily, block 67 "slides freely onthe rack bar without moving it. -When a coin -A coin duct 90, which isadapted to re- A detent pin 80, held in place ceive a coin released fromthe cup dispensing mechanism (not shown) extends. downward to a point"ust above the coin slot in block 67. A lea spring 91 having a flange 92at one end is fastened to the corn receptacle 68 and extends upwardly insuch a position pushed out of the way'and the coin'may drop into thecoinslot.

To prepare the machine for operation, the valve 9 is'opened, connectingthe carbonated water supply with the horizontal tanks 0,

and plunger zfis adjusted in cylinder it so as to adapt the cylinder toreceive the desired quantity of carbonated water. The stroke of plunger29 is adjusted, by adjusting lever 32 on plate 34, to pump the re quiredquantity of syrup.

. Cam 13 is positioned to elevate the valve 0 and thus shut off theconnection between the carbonated water supply and the measuring cup h.The roller 16 on block 15 is at the low point of cam 14.

The cup is placed in the holder 35 on the outside of the casing, beneaththe syrup nozzle and carbonated water nozzle. Assuming that a coin haspassed down the com duct 90into the coin slot in block 67,

- and that the lever 72 is then pulled downward, as heretoforeexplained, this movement of lever 72 rotates shaft 10, through pinion20, pawl 21 andratchet 22. As shaft 10 turns, lever 32 is actuated andcauses plunger 29 to force syrup from well 27, up pipe 31, and into thecup and causes the plunger to again rise, permitting the well to refill.

The rotation of shaft 10 causes cams 13' and 14 to turn. The high pointof cam 13 moves away from roller 6, permitting valve 00 to assume itslower position on seat w under the. influence of spring 7, openingcommunication between the cylinder k, which acts as a measuring cup, andthe tanks 0 through passage 3 in the Valve casing and pipe n, causingthe measuring cup to fill with carbonated water.

- Cam 14turns on roller 16, forcing block 15 down and tensioning spring17.

The rack advances turning the shaft 10 and the cams as above describeduntil'the cams assume the position shown in Fig. 7, with cam 13 about toraise roller 6 on the valve tappet and the roller 16 about to leave thehigh point of cam 14. In the movement of the hand lever, thev forked rod83 is advanced so that a light continued movement of shaft 10 will causearm 85 to contact with shoulder 81 and stop further movement.

A slight further movement of the rack caus'esblock 15, under theinfluence of thetension set up in spring 17, to kick cam 14 around, asroller 16 goes off the high point of the cam, causing cam 13 to raisevalve w,

, seating it on seat 1) and causing pilot valve z to close oil passage 3at the same bination of a measurin time opening communication betweenthe cylinder h and nozzle t, allowing the carbonated water in thecylinder to discharge into the cup and mix with the syrup. \Vhen roller6 .is on the high-point of cam 13, arm 85 contacts with shoulder -84 andmotion handle reaches its initial position. It will be noted that whenthe lever is moved down it must be moved all the way down andthe coindropped out before it can be again raised, thus preventing any more thanone portion of syrup and water being obtainedwith onecoin.

The mufiler g and arrangement. of thefnoz zle t in pipe 8 prevents thewater from splashing and spitting out of the nozzle 1..

When it becomes necessary to wash out the machine, this may be done byattaching a hose to valve 0, opening the valve and turning on a supplyof Water. v
